Question

A circuit is constructed with an AC generator, a resistor, capacitor and inductor as shown. The generator voltage varies in time as e =Va - Vb = emsin?t, where em = 120 V and ? = 209 radians/second. The inductance L = 179 mH. The values for the capacitance C and the resistance R are unkown. What is known is that the current in the circuit leads the voltage across the generator by f = 48 degrees and the average power delivered to the circuit by the generator is Pavg = 99 W.

What is C, the value of the capacitance of the circuit?
